Abstract
The genes of top athletes are a valuable genetic resource for the human race, and could be exploited to identify novel genes related to sports ability, as well as other functions. We analyzed the expressed sequence tags from top half-pipe snowboarding athletes using the SMART complementary DNA (cDNA) library construction method to elucidate the characteristics of the athlete genome and the differential expression of the genes it contains. Overall, we established a full-length cDNA library from the lymphocytes of half-pipe snowboarding athletes and analyzed the inserted gene fragments. We also classified those genes according to molecular function, biological characteristics, cellular composition, protein types, and signal paths. A total of 201 functional genes were noted, which were distributed in 27 pathways. TXN, MDH1, ARL1, ARPC3, ACTG1, and other genes measured in sequence may be associated with physical ability. This suggests that the SMART cDNA library constructed from the genetic material from top athletes is an effective tool for preserving genetic sports resources and providing genetic markers of physical ability for athlete selection.

Abstract
Genetic contribution has been consistently implicated in several neurological disorders, however only a fraction of candidate genes can be directly linked to these disorders. Many known risk factors for psychiatric diseases are related to the enzymatic regulatory machinery of the actin based cytoskeleton of neuronal cells. Synaptic plasticity which is fundamental for neuronal function heavily relies on actin-polymerization. To gain insight into the neuronal architecture during actin-related pathologic conditions, using quantitative electron-microscopy, the authors investigated a conditional knock-out mice breed, in which they studied the result of the postnatal loss of ArpC3 subunit of the Arp2/3 complex an evolutionary conserved final output of actin signalling pathways that orchestrates de novo actin polymerization. They found, that in the hippocampus which is a particularly favourable model for synaptic plasticity and believed to play a key role in learning and memory and neocortex, synaptic architecture is significantly altered compared to the wild-type. Their results suggest that dysregulation of the actin cytoskeleton results in pathologic neuronal architecture which may contribute to the ethiology of complex neurological disorders.
